In some GitHub actions, you can pass an arbitrary R vector in and we will
parse it. Unfortunately, this can lead to the insertion of malicious code,
so this function will thrown an error if the submitted R expression is
anything but a vector created with c(),
Usage
verify_simple_vector(inputs)
Arguments
- inputs
an R expression
Value
nothing. this is called for its side-effect. if inputs is not a
simple vector, an error will be thrown.
Examples
# simple vectors work.
try(vise::verify_simple_vector(c(1, "a", c(TRUE, FALSE))))
# vectors using any other function fail, even if they are harmless
try(vise::verify_simple_vector(c(1, print("a"), c(TRUE, FALSE))))
